5-HTP is derived from a natural source: the seeds of the African plant, Griffonia simplicifolia and includes added vitamin B-6, which is necessary for 5-HTP to be converted to serotonin. In many studies, 5-HTP has been shown to be more effective in promoting sleep than melatonin. This amino acid derivative has also shown promise for improving mood.

5-HTP is a precursor to a neurotransmitter called serotonin, which is involved in sending messages through the nervous system contributing to a person’s mood and well being. Supplementing with 5-HTP can increase serotonin levels, which in turn minimizes conditions associated with low serotonin levels, which include sleep and mood problems.

Side effects from supplementation with 5-HTP are generally mild and limited to nausea, constipation, gas, drowsiness or a decreased sex drive.
